Portland legal technology company Zapproved said Tuesday that it has sold most of the company to a private equity firm.

Vista Equity Partners did not say just how much it has invested in Zapproved, but the two organizations said the money will help finance the Portland company's growth. Vista's investment comes from a fund earmarked for business software companies with sales under $30 million.

Vista is the same firm that bought another Oregon company, Navex Global, for $524 million in 2014.

Both Navex and Zapproved operate in the legal and regulatory compliance sectors, but their specific markets are different and Zapproved said it is in a different Vista fund from Navex.

Founded in 2008, Zapproved helps companies locate and preserve data they must retain for litigation. The company had previously raised $20 million, including a $15 million round in 2015. Zapproved said Vista bought out some of its early backers, with hearty returns on their investments.

Headquartered in Portland's Pearl District, Zapproved employs 100, double what it had two years ago.
